Commerce labs (Monash perspective)
For business statistics subjects, you will have computer labs that are typically 90 minutes long, though you may finish the work in as little as 30 minutes or less, at which point you can just leave. Basically, you walk into the room, sit down at a computer, open the Excel file with the week's questions, and get to work. Some of the weeks (around half, in my experience) will be "submission weeks," where you have to submit your finished work online by the end of the lab to get it graded. If it's not a submission week, you can just save your work when you're done and then leave, though nobody's going to check your work so you can basically leave whenever you want (a lot of people choose not to show up at all on non-submission weeks). There is a lab supervisor to help you if you have any problems/questions, but otherwise, they're not very involved. Don't expect to make many friends during this class; people generally just get in and out as soon as possible.
